IMPROVEMENT IN STEAM-BOILERS.

Specification forming part of Letters Patent No. 141,172, dated July 22, 1873; application tiled February 6, 1873. v

To all whom it may concern:

Be it known that I, SEBASTIAN RITTY, of Dayton, in the county of Montgomery and State of Ohio, have invented certain Improvements in Steam-Boilers, of which the following is a specification:

My invention relates to a manner otl securing,beneatl1 and in connection with an ordinary steam-boiler, a series of tubes, which embrace the furnace and combustion-chamber, and which extend the entire length of the former.

The figure is a side elevation of the improved steam-engine boiler.

A represents an ordinary cylindrical steamboiler, constructed in the usual manner. H is the man-head, and D a series of tubes. A series of holes are drilled through that part of the boiler embraced by the part or division K, thus securing a communication between the cylindrical boiler and tubes. O is the furnacefront, having a door, C, the frame ot' which extends through the supporting-plate E. The division K is a closed vessel riveted onto the boiler, has parallel sides, and extends downward beneath the furnace. It has an orifice through its center, indicated by dotted lines, for the products ot' combustion to pass through. An arm-hole is shown at L. B represents a series of tubes with closed outer ends, and the inner open ends of which are secured to the central division, the outer ends being supported by the plates E and F. The rear supporting-plate is held in position by the rivets m, which secure it to the plate G, and the front plate E is supported in like manner.

The rear plate Gr serves to give direction to the products of combustion, and, in part, may be substituted by a brick wall. The tubes occupy all the space from beneath the furnace to the boiler, with the exception of furnacespace. These tubes may serve asgrates, or grate-bars may be placed Within the tubes.

The operation may be described thus: The boiler is supplied with Water; a lire being built Within the furnace, the products ot combustion pass through the central division, are diverted at the back' through the lines of the boiler, thence to the chimney.

The exposure of numerous tubes to the action ot' lire generates steam more eft'ectually than is done with the ordinary steam-boiler.

What I claim as my invention is- A The arrangement ot' the boiler A, hollow division K, and tubes B B, substantially as described.
